Beans, legumes, nut butter... Dont have to be pricey. Plus is you move into less meat you also cut down the not so great things that meat can also offer. Meditation is free, you can do it at home. You can exercise for free, dont need a gym pass, same as yoga. You could probably even find a free bike on freecycle.com or other places. I went gluten free, but I don't buy much of the gluten free food. It's not needed, I stick to veggies, fruit, protien, and grains that I can have.

I have 3 kids, and I live on $1,300 ( Canadian ) a month, I also live in a pricey valley, in a pricey province, cost of living is quite high here. Yet we all have bikes, we snowboard, we play tennis, skate, can go jogging and hicking, swimming, roller blading ... And eat healthy. It's doable, you just have to get creative, and find otherways to meet your needs. Thrift stores are a good place to get sporting equipement. Living a healthy lifestyle doesn't need to cost a lot of money.
